DISPENSING-CAN.

SPECIFICATION forming part of Letters Patent No. 675,820, dated June 4,1901.

Application filed October 24, 1900. fierial No. 34,189. (No model.)

To ItZZ whom, it Hui/y concern:

Be it known that I, BENJAMIN G. DEvoE, a citizen of the United States,residing at Lima, in the county of Allen and State of Ohio, haveinvented new and useful Improvements in Dispensing-Cans, of which thefollowing is a specification.

This invention relates to new and useful improvements in dispensingcansespecially adapted for use in filling lamps, &c., and its primary objectis to provide means whereby the oil may be readily discharged into alamp or other receptacle under air-pressure.

A further objectis to provide means whereby the flow of oil from the canmay be readily regulated.

Another object is to so construct the device that any undue amount ofoil within the lamp, 850., may be automatically returned to thedispensing-can.

\Vith these and other objects in view the invention consists inproviding a can upon which is mounted an ordinary hand-pump. Thecylinder of this pump communicates with the interior of the can througha tube or other similar device. An aperture is arranged within the topof the can and is adapted to be closed by means of a cap formed at oneend of a lever. Means are provided whereby the cap is held normally inposition over said aperture. A siphon extends upward through the top ofthe can and the discharge end thereof is arranged at a point above thecan, while the inlet end lies adjacent to the bottom thereof.

The invention also consists in the further novel construction, 850.,hereinafter more fully described and claimed, and illustrated in theaccompanying drawings, showing the preferred form of my invention, andin which- Figure 1 is a side elevation of the device, and Fig. 2 is alongitudinal section therethrough.

Referring to said figures by numerals of reference, l is a can of anydesired form and material having standards 2 thereon, upon which ismounted a pump-cylinder 8. This cylinder is secured to the standards inany suitable manner and may, if desired, be detachably secured thereon.A valved piston 4 is mounted within the cylinder and operated in anysuitable manner, as by means of a knob 5, connected to the piston by therod 6.

An aperture 7 is formed within the top of the can and is adapted to beclosed by means of a cap or closure 8, preferably formed of rubber. Thiscap is secured at the lower end of a lever 9, which is fulcrumed uponone of the standards 2, before referred to, and the outer end of whichforms a curved handle 10, whereby the cap may be swung upward away fromits seat. A spring 11 is arranged between the handle 10 and the top ofthe can and serves to hold the cap 8 normally in position over theaperture 7. A siphon 12 extends through and is revoluble within the topof the can 1, suitable packing 13 being provided, so as to prevent theescape of air through the joint. The short arm 14 of the siphonterminates at a point above the top of the can, while the arm 15 passesdown into the can to a point adjacent to the bottom thereof.

Oil is placed in the can in any suitable manner, as through the aperture7, and the lever 9 is released, permitting the cap 8 to flow intoposition over said aperture. The piston 4 is then moved back and forthwithin the cylinder 3, forcing the air downward through the tube 16,which connects said piston with the interior of the can. When suflicientpressure has been obtained within the receptacle, the oil will be forcedupward through the siphon and will be discharged from the end of the arm14 thereof. A sufficient amount of air may be forced into the receptacleto fill the lamp, and when such lamp is filled and it is desired to stopthe flow of oil it is merely necessary to depress the handle 10 of thelever. This will raise the cap 8 and the air will flow outward throughthe aperture 7, thereby removing pressure from the oil within thereceptacle. Should too much oil bedischarged into the lamp, a portionor, if desired, all of the oil may be returned to the dispensingcan byretaining the outlet end of the siphon below the level of the oil withinthe lamp. The oil will then be returned to the dispensing-can bysiphonic action.

\Vhen it is desired to fill the can with oil, the piston at is slidinward, causing the knob 5 thereof to contact with the curved lever andforce the same downward, thereby raising the cap or closure 8 at the endof said lever. This cap will be held in this position while the oil isbeing placed within the device, and as soon as the piston is movedoutward the cap will be returned automatically to its closed position bythe spring 11.

In the foregoing description I have shown the preferred form of myinvention; but I do not limit myself thereto, as I am aware thatmodifications may be made therein without departing from the spirit orsacrificing any of the advantages thereof, and I therefore reserve theright to make all such changes as fairly fall within the scope of myinvention.

Having thus fully described myinvention, what I claim as new, and desireto secure by Letters Patent, is-

1. A device of the characterdescribed, comprising a can having anaperture therein; a cylinder mounted thereon; a piston within thecylinder; a knob connected to the piston; a tube connecting the cylinderwith the interior of the can; an outlet from the can; alever journaledupon the can and normally closing the aperture therein; and means forholding the lever in position over said aperture, the knob of the pistonbeing adapted to depress the lever and hold the same raised from theaperture.

2. A device of the character described comprising a can, a cylindermounted thereon, a piston within the cylinder, a knob connected to thepiston, a tube connecting the cylinder with the interior of the can, asiphon, one arm of which extends into, and is revoluble within, the can,said can having an outlet therefrom, a lever journaled upon the can, acap thereto adapted to close the outlet, and a spring for holding thecap normally in position over the outlet, the knob of the piston beingadapted to depress the lever and hold the cap thereof raised from theoutlet.

3. Adevice of the character described comprising a can having anair-inlet, standards upon the can, a pump-cylinder secured upon thestandards, a tube connecting the pumpcylinder with the interior of thecan, a reciprocating piston within the cylinder, a knob connected tosaid piston, a siphon, one arm of which extends into, and is revolublewithin, the can, a lever fulerumed upon one of the standards, acap atoneend of the lever adapted to close the outlet, a curved handle at theopposite end of the lever, and a spring for holding the cap normally inclosed position over the outlet, said knob being adapted to contact withand depress the curved handle and hold the cap in raised position.

In testimony whereof I affix my signature in presence of two witnesses.

BENJAMIN G. DEVOE.
